2023 ‘smashes’ records
RECORD-SHATTERING: 2023 “smashed” the record for the hottest year by a large margin, reported the Guardian. The newspaper said on Tuesday that, according to the EU’s Copernicus Climate Change Service, 2023 was 1.48C hotter than pre-industrial times. This is 0.17C higher than the last record set in 2016 – “marking a very large increase in climate terms”, according to the Guardian. And today the record was confirmed by the UN’s World Meteorological Organization, which has just published the findings of six leading climate datasets.
CHARTING CHANGE: In its coverage of the data, BBC News produced a number of charts and figures illustrating the path of global warming. Its analysis showed that almost every day since July has seen a new global air temperature high for the time of year. Meanwhile, the Independent published a feature examining whether 2024 could be even hotter than 2023.
STATE OF THE CLIMATE: Carbon Brief has just published the last of its quarterly state of the climate updates for 2023. It explains that 2023 was the warmest year “by a large margin”, at between 1.34C and 1.54C above pre-industrial levels across different datasets. Last year was also the warmest on record for ocean heat content, which increased notably between 2022 and 2023.
UK MP quits over fossil fuels
‘TRAGEDY’: The UK’s former energy minister Chris Skidmore quit as an MP in protest at the government’s plans to drill for more oil and gas in the North Sea, the Financial Times reported. In his resignation letter, Skidmore said it was “a tragedy that the UK has been allowed to lose its climate leadership” under prime minister Rishi Sunak, according to the newspaper.
BILL DELAYED: Skidmore quit over the government’s offshore petroleum licensing bill, which aims to “maximise” new oil and gas production, the FT said. The bill was due to be read in the House of Commons this week, but ended up being postponed, the Times reported. BBC News reported that Sir Alok Sharma, the Conservative MP and COP26 president, said he would vote against the bill, calling it “a total distraction” which reinforces the idea the UK is “not serious” about tackling climate change.
Renewables on the rise
RECORD RENEWABLES: A boom in Chinese solar power drove another record-breaking year of renewables growth in 2023, according to a new International Energy Agency (IEA) report covered by Carbon Brief. The world is now on track to build enough solar, wind and other renewables over the next five years to power the equivalent of the US and Canada combined, according to Carbon Brief’s analysis of the findings.
UK SOLAR: Along with the increase in global renewable capacity, there has been continued growth in low-carbon upgrades on UK homes, with solar and heat pumps driving record installations in 2023, according to separate Carbon Brief analysis.
Around the world
- US COAL DROP: US emissions fell by 1.9% in 2023, largely due to coal declining to its lowest level in 50 years, the New York Times reported. By contrast, US oil and gas production is set to hit a record in 2024 and 2025, said the Financial Times.
- ‘A LA CARTE’: Saudi Arabia’s energy minister has claimed that the headline COP28 agreement to transition away from fossil fuels is just one of several “choices” on an “a la carte menu”, reported Climate Home News.
- WAR EMISSIONS: Israel’s assault on Gaza since 7 October has produced more greenhouse gas emissions than 20 of the world’s most climate-vulnerable countries create in a year, according to new analysis covered by the Guardian.
- GERMANY PROTESTS: Farmers took to the streets of Berlin to protest against the German government’s decision to cut agricultural subsidies, Deutsche Welle reported.
- DEEP SEA MINING: Norway has become the first nation to approve commercial deep-sea mining, opening up a vast area of the Arctic to the extractive practice despite warnings from scientists, Mongabay reported.
- OFFSETS CONTROVERSY: The first-ever carbon-offset exchange under a new Paris Agreement mechanism, involving Switzerland buying credits for the rollout of electric buses in Thailand, is facing integrity questions, Climate Home News said.
40%
The proportion of North Sea oil and gas licences in UK waters owned by foreign companies and investors, according to EnergyMonitor.
Latest climate research
- A new research paper in Nature Climate Change presented a “conceptual framework” for considering the role of justice within climate research.
- The presence of urban green space is associated with “significantly lower rates of violent crime committed outside”, according to an International Journal of Biometeorology study conducted in Australia.
- A pair of studies in the Journal of Climate delved into an “exceptional heatwave” in east Antarctica in 2022, which brought “widespread 30-40C temperature anomalies across the ice sheet”.

Captured

A record 42 editorials opposing action to tackle climate change were published by UK newspapers in 2023, according to new Carbon Brief analysis. Written almost exclusively by right-leaning papers, these editorials called for delays to UK bans on the sale of fossil fuel-powered cars and boilers, as well as for more oil-and-gas production in the North Sea, according to the findings. In response to such demands, prime minister Rishi Sunak performed a “U-turn” in September on some of his government’s major net-zero policies.
Spotlight
Investigating Antarctica’s colossal icebergs
This week, Carbon Brief speaks to Dr Oliver Marsh, a glaciologist who is principal investigator of a British Antarctic Survey (BAS) mission currently studying iceberg calving events at Antarctica’s Brunt ice shelf (pictured).

Carbon Brief: Can you please explain what fieldwork you are currently working on?
Dr Oliver Marsh: We are drilling ice cores to collect ice samples from the Brunt ice shelf. These will be brought back to Cambridge [where BAS is located] and University College London (UCL) in order to test their physical and chemical properties. We are also setting up seismic and GPS equipment to monitor fracture growth and strain rates on the ice shelf. We will then link the properties of the ice to the behaviour of the fractures.
CB: What do you hope to find out by conducting this fieldwork?
OM: We are interested in the mechanism and timing of crack growth leading to iceberg calving [where chunks of ice break off from the front of a glacier]. In particular, we want to understand how changes in ice properties change calving rates. The ice shelf we are working on has a well-documented history of crack growth, with two large calving events in the last three years, and the new information we gain from precise laboratory measurements will help us to understand how – and under what conditions – fractures occur in the lead-up to these calving events.
CB: What are the biggest hazards with conducting fieldwork on the Brunt ice shelf?
OM: The Brunt ice shelf is a good location to monitor fracture growth due to its dynamic behaviour. This means there are rifts and other cracks in the ice that can be hazardous for travel. These cracks are heavily monitored with a suite of geophysical instruments, including ground-penetrating radar, GPS and satellite data, and precautions are taken when moving around. Fieldwork in Antarctica also has significant hazards associated with the weather, for example, strong winds and wind chill.
CB: How is climate change affecting iceberg calving events in Antarctica?
OM: Calving occurs as a normal process of ice loss from the continent. But, as it occurs in discrete events and very infrequently for some ice shelves, it is difficult to determine whether rates are changing from a short satellite record. Other fracturing processes, such as hydrofracture and ice shelf collapse, are linked to both ocean and atmospheric warming, so it is possible that calving rates may increase in the future.
CB: What would be the implications of accelerated iceberg calving for the climate and ecosystems?
OM: Increased calving is likely to weaken ice shelves that fringe the continent and support the glaciers inland. This can help to speed up glacier flow and ice loss to the ocean, contributing to sea level rise. An increase in the volume of icebergs may also cause issues for ecosystems, particularly in areas where icebergs ground on the ocean floor, blocking foraging routes for penguins and seals, for instance.

Will new UK PM’s green measures at home cause climate finance pain overseas?
Britain’s new prime minister announced in his first week that he will cut the cost of public transport and electricity, making lower-emission technologies like bus travel, electric vehicles and heat pumps more affordable for voters. But some of the funding for those policies will come from the budget for international climate finance, the government has said, raising concerns about fairness.
Former Manchester Mayor Andy Burnham took over from Keir Starmer as Labour Party leader and prime minister on Monday, appointing climate advocates Ed Miliband as foreign and development minister and Miatta Fahnbulleh as climate and energy minister.
On Tuesday, Burnham said his government would cut the value added tax (VAT) households and some small businesses pay on their electricity bills from 5% to zero from October 1, saving households £45 ($60) a year.
On Wednesday, he said the maximum fare bus companies in England can charge for a single journey will be reduced from £3 ($4) to £2 ($2.67) from January 1, 2027. The government said the subsidies to achieve this would be mostly funded by switching money set aside for overseas climate finance projects from grants to loans. It did not give further information in its announcement, while the UK’s transport minister told Sky News the plan is still being worked out.
The floated changes to the climate finance budget were immediately criticised by groups working on climate justice for developing countries, including Bond, the UK network for NGOs, which described the decision as “disappointing”.
“Robbing Peter to pay Paul is not the answer and pitches marginalised communities in the UK against marginalised communities in lower-income and climate-vulnerable countries,” BOND CEO Romilly Greenhill said in a statement. “Climate finance must not worsen the debt burden of countries that are already suffering the worst – and most costly – impacts of a climate crisis they did not cause.”
Hunt for money
Burnham promoted both policies as measures to combat the rising cost of living and “give people breathing space”, with climate campaigners and industry groups noting they are also likely to reduce the UK’s climate-heating emissions by encouraging bus travel and the use of electric vehicles and heating.
But thorny questions remain over how the policies will be paid for. The government said Tuesday’s VAT cut for electricity would be funded by scrapping the previous government’s digital ID programme, but Darren Jones, a former minister involved with that policy, said it had been “unfunded” – a statement that dominated media coverage.
A day later, the government said the new bus fare cap would cost £454 million ($606m). Transport minister Heidi Alexander told Sky News that £54 million would be taken from an under-spend in the budget of the Department for Energy Security and Net Zero (DESNZ) and £400 million would come from changing unspecified international climate finance from grants to loans. The details “still need to be worked through”, she said, adding that the government “had wanted to make an announcement today”.
Mohamed Adow, director of Nairobi-based think-tank Power Shift Africa, said “climate finance was never meant to be a pot of money that governments raid when they need to pay for domestic spending”.
DESNZ had not responded to a request for comment at the time of publication. “We’re not wanting to fleece anyone here, and we actually want to maximise the development potential of this money that is available,” minister Alexander said in her TV interview.

Aside from the controversy over their funding, the policies themselves were widely welcomed by climate campaigners. Jess Ralston, energy lead at the Energy and Climate Intelligence Unit (ECIU), said the tax cut on electricity bills “could help households to switch to electric heat pumps, protecting UK homes from becoming ever more exposed to the whims of Putin and Trump when turning on their gas boiler”.
The last few months have seen global momentum build behind electrification, spurred by the US-Iran war disrupting oil and gas supplies and driving up prices. The Turkish and Australian COP31 presidencies have announced a global target to boost electrification, backed by the European Union, Canada, Philippines, UK and others.
Campaigners call for lower power prices
While reaction to the VAT cut was supportive, some questioned whether £45 a year of savings per household is enough and called for more measures to cut electricity bills.
Friends of the Earth’s energy lead Imogen Dow said those on the lowest incomes should be given cheaper electricity through a “social tariff” and the Institute for Public Policy Research (IPPR) think-tank – which is close to the Labour Party – said levies on energy bills should be shifted to general taxation.
Matthew Paterson, a politics professor at Manchester University, told Climate Home News that the most effective way to reduce electricity bills is to take on the UK’s private electricity companies, while consumer-oriented measures like the VAT cut are “tinkering around the edges”.
Jarrod Birch, head of policy and public affairs for the EV charging industry association Charge UK, said that while the policy would make home-charging cheaper, people who charge their vehicles at public points will still have to pay 20% VAT. The UK’s tax authority is fighting a court ruling that ordered it to reduce the tax motorists pay on public chargers to the current household rate of 5%.
Further measures will be the responsibility of Secretary of State for Energy Security and Net Zero Miatta Fahnbulleh, who is relatively new to politics after a career at left-wing, pro-climate think tanks the IPPR and the New Economics Foundation.

Michael Jacobs, political economy professor at Sheffield University and former adviser to UK Labour prime minister Gordon Brown, said Fahnbulleh would be a “climate advocate” who would continue the “progressive climate agenda” of her predecessor Ed Miliband.
“She’s a very creative policy wonk so I expect there to be lots of policy innovation under her,” he said, “I think she will be looking at new ways to encourage take-up of heat pumps and domestic batteries.”
Aid budget in Miliband’s hands
Despite reports he could be made finance minister, Miliband has been appointed Secretary of State for Foreign and Commonwealth Affairs. Miliband has attended many climate COP meetings over several decades, most recently representing the UK at COP29 and COP30, and has been targeted by the right-wing media for his support for climate action and opposition to new oil and gas drilling in the UK’s part of the North Sea.
In his new role, Miliband will be responsible for the UK’s overseas aid budget including its international climate finance, which the Starmer government had slashed to fund increases in defence spending.
UK cuts support for climate action abroad to fund military instead
Jacobs said he expected Miliband to prioritise climate and development in the UK’s foreign policy and to push Burnham and new finance minister John Healey to reverse Starmer’s aid cuts.
But there are fears Healey could try to cut the aid budget further to fund the military. Healey was a surprise pick for Chancellor of the Exchequer and grabbed headlines when he resigned as Starmer’s defence minister in June over what he saw as insufficient defence spending.

Greenpeace launches legal challenge against Australia’s biggest meat company
AMSTERDAM, Netherlands, 22 July 2026 – Greenpeace Netherlands has launched legal proceedings against a multi-billion-dollar global expansion plan by the biggest meat producer in Australia, JBS, in an escalation of climate litigation against the livestock industry.
Greenpeace petitioned a Dutch court to compel the meat giant to disclose information in order to challenge its business policies in court, including a US$6 billion global expansion, for which almost half is earmarked for Nigeria.
Elizabeth Atieno, Food Campaigner at Greenpeace Africa, said: “JBS’ meat empire expanded hand-in-glove with Amazon destruction, colossal emissions, human rights and corruption scandals, all with barely a semblance of transparency. This is the business model it wants to export to sub-Saharan Africa. JBS promises food security, but its expansion in Nigeria risks causing irreversible environmental damage and the displacement of smallholder farmers to line the pockets of wealthy global elites.
“Nigerians know well from the legacy of companies like Shell the destructive impact wrought by unchecked corporate power. As Greenpeace Africa has argued before the African Court of Human Rights, states with jurisdiction over multinationals must hold those corporate actors accountable – wherever they operate in the world. We welcome this bold legal action: the Netherlands and other European states must not be safe havens for corporations like JBS seeking to evade their responsibilities.”
In light of JBS’ longstanding failure to publish accurate and reliable information on its climate, nature and human rights impacts or its expansion plans, Greenpeace Netherlands views accessing this data as a necessary precursor to formal litigation in order to support its case. The case has the potential to be the first climate litigation of this scale against the livestock industry. This could set a major precedent for future legal challenges against the industrial agriculture sector, a major source of global emissions, particularly of methane, a potent greenhouse gas, responsible for 0.5°C of warming since the Industrial Revolution.[1]
JBS, via its subsidiary JBS Foods Australia, is the largest meat and food processing company in Australia. With a weekly processing capacity of over 50,000 cattle, it accounts for almost a quarter of all beef processing in the country, as well as a significant presence in the lamb, pork and farmed fish markets. [2] In 2022, ABC’s Four Corners accused the company of ‘repeatedly failing to protect its workers from horrific injuries.’ [3]
Marieke Vellekoop, Executive Director at Greenpeace Netherlands, said “In a month where JBS has thrown its flagship environmental commitments onto the scrap heap, JBS’ disdain for basic transparency only adds to the impression that this meat giant has something to hide and is desperate to prevent its expansion plans from going public. We were hoping we wouldn’t have to trouble a judge with this matter, but JBS has left us no choice but to seek our right to information through the Dutch courts.
“JBS appears to believe that despite moving to the Netherlands, our rules do not apply to it. This legal action aims to prove it wrong – and lay the ground for a first major climate and nature lawsuit against the dangerous expansion of the global meat industry.“
At the centre of the dispute is JBS’ planned US$ 2.5 billion investment in industrial livestock production in Nigeria.[2] Civil society groups in Nigeria have raised urgent warnings that the aggressive expansion will threaten local food security, drive regional instability, and accelerate ecological degradation. There is no available evidence that JBS has conducted any impact assessments or community consultations in Nigeria, and local efforts to gather more information via Freedom of Information requests have reportedly been ignored.[3]
The escalation to the courts follows the refusal of JBS, the world’s largest meat company, to comply with a formal disclosure demand delivered by Greenpeace Netherlands in April. The environmental group is utilising new Dutch legislation, which grants parties with a legitimate interest the right to demand access to specific corporate data necessary to build litigation against Dutch companies.[4]
Greenpeace Netherlands’ lawyers allege that JBS’ historic business practices and future expansion plans are inconsistent with the company’s climate and biodiversity obligations and represent a breach of its Dutch duty of care, which requires companies to act in line with international human rights law.[5]
If the court rules in favor of Greenpeace Netherlands, it is entitled to seek the required information in the form of documents and from senior JBS figures under oath, raising the prospect of the Batista brothers being forced to testify in Dutch court. JBS reincorporated as a Dutch entity (JBS N.V.) last year to facilitate a dual listing on the New York Stock Exchange.
In April, JBS was forced to temporarily suspend its first annual general meeting since moving its headquarters to Amsterdam after it was disrupted by dozens of Greenpeace Netherlands activists.
Last week, JBS scrapped two flagship commitments to reach Net Zero emissions by 2040 and eradicate deforestation from its supply chain. It also removed any explicit reference to Indigenous lands from all of its current policies. Greenpeace Netherlands is concerned this indicates JBS is seeking to expand unconstrained by the climate, nature and human rights impacts of its business.

Notes:
[1] The livestock sector is estimated to be responsible for 31% of global methane emissions (more than oil and gas operations). In comparison to CO2, methane is shorter lived (around 12 years) but has a much stronger ability to trap heat in the atmosphere over its lifetime: it has approximately 80 times more climate impact than CO2 when measured over 20 years. This means that changes in methane emissions have a more rapid effect on the climate than changes in CO2. See Greenpeace Netherlands letter to JBS dated 30 April 2026.

“Next year is too late for regulations”: Beetaloo Energy’s 2GW gas-powered AI data centre a “disaster proposal” destined to cause climate chaos
SYDNEY, Wednesday 22 July 2026 — Beetaloo Energy has secured land from the NT Government for a massive $40 billion “hyperscale” AI data centre near Darwin, which would be powered by 2 gigawatts (GW) of gas power fracked directly from the Beetaloo basin, prompting calls from Greenpeace for urgent federal legislation.
The proposal marks a dangerous escalation in the AI data centre industry’s expansion, which threatens to entrench fossil fuel infrastructure for decades and put immense pressure on the region’s fragile water resources — while continuing to be unregulated.
Joe Rafalowicz, Head of Climate and Energy at Greenpeace Australia Pacific, said: “This disaster proposal for a 2GW gas-powered AI data centre in the NT is a shocking example of the unchecked expansion of hyperscale data centres in Australia. It is also, critically, more evidence for the urgent need for a moratorium on all new data centres until strong, binding regulations are put in place to protect our communities and climate.
“This proposal mirrors the frenzied, unchecked expansion currently wreaking havoc on communities in the US. We are seeing cowboy data centre operators treat Australia like a playground, steam-rolling ahead with projects that would lock down precious water resources and spike emissions, despite the overwhelming community opposition.
“Every day, more councils, communities and environmental groups are joining Greenpeace’s call for a moratorium on data centres, yet as of today there is still no system of safeguards or rules in place to regulate these companies.
“While Beetaloo Energy and the NT Government prepare to bulldoze ahead with this climate and water disaster, the Prime Minister is asleep at the wheel, promising to legislate a vague set of standards next year.
“Next year is too late, and anything less than mandating data centres cover their own energy demand, and then some, with new renewable energy is not enough.”
